To all 'Lu/710m 't :may conccr'n:

Be it known that I, ArsnN G. l-owAnD, a citizen of the United States,residing at Holdrege, in the County of Phelps and State of `Nebraska,have invented a new and useful Improvemenet in Hoof-Trimmers, of whichthe following is a specification.

r[his invcntion relates to hoof trimmers for trimming the hoofs ofanimals, the objcct being to provide a device by means of which thehoofs of an animal can be easily and quickly trimmed without any dangerof being hurt. V

A further object of the invention is to provide a hoof trimmer which isprovided with a Cutting tool operated by a sliding hammer carried by arod whereby said'tool can be operated by moving the rod up and down soas to cause the hammer to strike the tool a blow.

A furthcr object of the invention is to provide a hoof trmmer which isexceedingly simple and cheap in construction and one which is composedof a few parts which are so mounted thatthey Can be readily taken apartwhereby any of the parts can be readily replaced should they becomebroken.

A still further object of the invention is to provide a hoof trimmerwhich is so constructed that the hoofs of an animal can be trimmed by aperson holding the device when in an upright position whereby all dangerof being kicked by the animal is prevented.

A still further object of the invention is to provide a Cutting toolwhich is returned to its normal position by a spring, said spring beingCompressed by the force of the blow of the hammer.

A further object of the invention is to provide means for adjusting thetension of the spring said means forming a stop for the Cutting toolwhereby the upward movement of the same will be Controlled.

wvVith these objects in view, the invention consists of the novelfeatures of construction, combination and arrangement of partshereinafter described, pointed out in the claims and shown in theaccompanying drawings, in which,

Figure 1 is a side elevation of my improved hoof trimmer. Fig. 2 is avertical section through the same. Fig. 8 is a section taken on line 8-3of Fig. t.

In Carrying out my improved invention I employ a frame A provided with across bar A' having an enlarged apertured portion A2 through which isadapted to extend a cutting tool B which is slidablv mounted within anopening .formed in tne bottom of the frame and is surrounded by ay Coilspring O the lower end of which bears against the bottom of the frameand the upper end against a Collar D seCured on the tool by a set screwD' said collar forming a stop for limiting the upward movement of thetwo and it will be seen that as the tool is forced downwardly the springwill be compressed and as it is released it will be forced upwardly bythe spring until the Collar engages the cross bar.

This tool may be of any desired shape but is preferably in the form of achisel so that it can be readily placed over the edge of a hoof of theanimal so that when the same is forced downwardly the edge of the hoofwill be cut off.

For Operating the Cutting tool I employ a hammer E provided with avertical bore in which is secured a rod F by a set screw F' said rodworking in a tube Gr secured in the upper end of the frame A and havinga handle H formed on its upper end for operating the same and it will beseen that by raising the hammer and forcing the same downwardly quicklythe hammer will be brought into engagement with the top of the Cuttingtool so as to cause the same to cut through the hoof when placedthereon. By this arrangement the hoof of the animal can be trimmed by aperson standing in an upright position and it is only necessary to graspthe tube of the frame with the hand and guide the tool on the hoof inthe desired position, it of course being understood that the animal isstanding on a flat surface, and by raising the hammer upwardly andforcing the same downwardlya blow will be struck upon the Cutting tooland it will be seen that by repeating this operation the hoof Can betrimmed easily and quickly without any danger of the operator being hurtby the animal as in some cases it is necessary to throw the animal downbefore the hoof can be trimmed. It is only necessary to force the hammerdown with a slight pressure as the weight of the same dropping by itsown weight will strike a blow upon the Cutting tool with sufficientforce to trim the ordinary hoof.

From the foregoing descriptlon 1t will be seen that I have provided ahoof trimmer which is so constructed that it can be readily handled andat the same time it can be operated by one hand thereby enabling` theoperator to trim the hoof of an animal quickly. It will also be seenthat this device can be used for other purposes as by removing` theCutting' tool and placing a punch or any other tool Within the same itcan be used for punching holes or Cutting material of other characters.

7hat I claim is l. A hoof trimmer comprising a frame provided With anapertured cross-bar in alinement With an aperture formed in the bottomof said frame, a tool slidably mounted Within said aperture, a collarsecured on said tool forming a stop for the same a spring` surrounding`said tool between the bottom and said collar, a tube carried by saidframe and a rod slidably mounted within said tube carrying a hammer forengaging said tool.

2. A hoof trimmer comprising a frame provided with an opening in itsbottom, a cross bar arranged in said frame provided With an opening inalinement With the opening` of the bottom, a tool slidably mountedWithin said openings, a col-spring surrounding said tool, a. collarsecured on said tool adapted to engage said cross bar, a tube carried bysaid frame, a rod provided With a handle at its upper end slidablymounted Within said tube and a halnmer carried by the lower end of saidrod adapted to engage said tool.
